Bruno P. Kinoshita commented on IMAGING-198:
--------------------------------------------
Managed to debug a bit more today. The reader is iterating the dirs in the
metadata. And by default the JPEG reader asks the TIFF metadata reader to parse
thumbnails.
When it parses the first directory, it correctly reads the thumbnails location.
But as it's iterating through directories, the current ByteSource contains the
bytes for that directory only and hence the exception. The current ByteSource
bytes are around 700, but the location of the thumbnails start at the offset
~2000 up to ~7000.
